BRIANLIST AND 50 POINTS SHOW EVERY CALCULATIONS YOU DID

1. 0.5 g of salt is equal to how many milligrams?
2. A watermelon weighs 6.45 kilograms. How many grams does the it weigh?
3. A box of oranges weighs 4 kg. If one orange is 80 kg how many oranges are in the box?
4. Peter weighs 105 kg. He wants to lose 500 g per week. How many weeks will it take for him to have a mass of 90 kg

1) 500mg/1000 = 0.5g of salt. So, 200mg of sodium equals 500 mgs or 0.5g of salt.

2) 6540 multiply the mass value by 1000

3) Instead of 80kg im thinking that you ment g

Weight of box = 4 kilograms

1 kg = 1000 g

4kg = 1000*4 = 4000 grams

Therefore,

Weight of box = 4000 g

Weigh of one orange = 80 grams

Let,

x be the number of oranges in box.

80x=4000

Dividing both sides by 80

There are 50 oranges in the box.

4) 30weeks

Step-by-step explanation:

From the question given,

Peter's weight = 105kg

Now, Peter wants to lose 500g per week i.e

Peter wishes to lose = 500/1000 = 0.5kg per week.

The mass losed by Peter = 105 —90 = 15kg

Now if Peter losed 0.5kg in 1week, then he will lose 15kg in = 15/0.5 = 30weeks

Therefore, it will take Peter 30 weeks to have a mass of 90kg
